Koj sit tangy cola, txaus siab rau ib daim ntawm cov cheese, lossis lob ib lub ntim ci ci. Txoj kev sib luag yog, ib qho kev sib txawv tab sis feem ntau tsis nkag siab cov khoom ua si ua si lub luag haujlwm: phosphoric acid. Tshwj xeeb, Khoom noj me me, cov zaub mov qib phosphoric acid - ib daim ntawv ua kom huv ntawm orthophosphoric acid - yog ib qho haujlwm ua haujlwm hauv kev lag luam khoom noj. Tab sis dab tsi xyov yog nws, vim li cas nws siv, thiab puas muaj kev nyab xeeb? Cia peb ntsaub mus rau hauv lub ntiaj teb ntawm phosphoric acid hauv cov zaub mov.
What is Phosphoric Acid & Its Food-Grade Cousin?
Ntawm nws cov tub ntxhais, phosphoric acid (h idpo₄), CAS: 7664-38-2, tseem paub hom tshuaj astophosphoric acid, yog cov roj av ntxhia plab. Nws yog ib txwm muaj nyob rau hauv ntau cov zaub mov xws li nqaij, nplej, thiab txawm tias mis los, albeit nyob rau hauv me me. Txawm li cas los xij, cov phosphoric acid siv los ntawm cov khoom noj khoom noj yog synthetically tsim los kom ntseeg tau kev coj dawb huv, xwm yeem, thiab siab xav.
Nov yog cov zaub mov qib phosphoric acid los rau hauv. Nws undergoes txoj kev lim dej kom tau raws li cov qauv kev nyab xeeb raug teeb tsa los ntawm kev tswj hwm lub cev zoo li lubFDA(hauv Asmeskas) thiab covTxoj Cai Nyab Xeeb Nyob Sab Europe(EFSA). Cov qauv no (zoo li tusTshuaj Noj Tshuaj Noj Codex{{0- FCC) Tsis tshua muaj kev txwv tsis pub zoo li cov hlau hnyav dua li cov hlau hnyav (cov tshuaj tua tsiaj, ua kom nws muaj kev nyab xeeb rau kev noj. Qhov tseem ceeb, kev lag luam - qib phosphoric acid tsis haum rau cov khoom noj - tsuas yog cov zaub mov- qib ntau yam yog siv.
Vim li cas phosphoric acid ntxiv rau cov khoom noj?
Khoom noj khoom haus qib phosphoric acid ua haujlwm rau ntau lub zog tseem ceeb, ua rau nws muaj ntau yam khoom siv rau cov kws tshawb fawb khoom noj:
1. Cov kua qaub ua haujlwm: Qhov no yog nws lub luag haujlwm nto moo tshaj plaws, tshwj xeeb tshaj yog hauv cov dej qab zib xws li colas thiab lwm yam dej qab zib. Nws muab cov ntse, tangy, qaub saj uas cov neeg siv khoom ntshaw. Qhov tseem ceeb, nws txo qis lub pH (nce acidity) ntawm cov zaub mov thiab dej qab zib. Qhov no acidic ib puag ncig:
- Txhim kho cov tsw thiab tartness.
- Ua raws li cov tshuaj tiv thaiv, inhibiting txoj kev loj hlob ntawm cov kab mob, pwm, thiab cov poov xab, txuas lub neej.
- Pab tsim cov gels nyob rau hauv qee kis thiab jellies.
- AIDS hauv cov txiaj ntsig ntawm lwm cov tshuaj txuag zoo li benzoates.
2. Main Enhancer: Tshaj dhau ntawm kev txaj muag, phosphoric acid tuaj yeem pab sib npaug zuag qhia tag nrho cov khoom lag luam, ua lwm yam flavors "pop."
3. Cov khoom noj muaj txiaj ntsig: phosphorus yog ib qho tseem ceeb ntxhia rau tib neeg kev noj qab haus huv (cov pob txha tsev, thiab koom nrog lub zog metabolism). Khoom noj khoom haus qib phosphoric acid thiab nws cov ntsev (zoo li calcium phosphate, sodium phosphate) yog siv rau kev noj zaub mov thiab dej haus, ntxiv cov tshuaj phos kom zoo nkauj. Nws muaj ntau nyob rau hauv pluas tshais cereals, ua cov khoom noj ua mis nyuj, thiab dej haus zoo.
4. Seastering Tus Neeg Sawv Cev: Nws khi rau cov hlau ions (zoo li cov qos yaj ywm, zoo li nqaij ntses lossis dej hiav txwv. Qhov no pab khaws cov khoom xim, tsw, thiab kev ruaj khov.
5. Cov tshuaj ntsuab cag ntoo: hauv ci hmoov, ntsev tau muab los ntawm phosphoric acid (zoo li cov roj ntsha ua kom cov roj carbon dioxide, ua rau khob noom cookie thiab batters kom sawv.
6. Cov tshuaj tiv thaiv protein: hauv cov cheese ua (tshwj xeeb cov cheeshes thiab cov ntsev kis thiab tso dej, tsim kom muaj cov tshuaj du, zoo nkauj, suab paj nruag zoo nkauj. Nws kuj tseem yuav pab tswj cov mis nyuj uas muaj cov mis nyob hauv cov mis nyuj qab haus.
Cov khoom noj uas muaj cov kua hluav taws xob muaj kua hluav taws xob posphoric acid:
- Kev haus dej haus dej (tshwj xeeb yog colas): thawj qhov chaw ntawm tanginess.
- Cov cheess thiab cheese kis: rau kev ntxhib los mos thiab emulsification.
- Pluas tshais ua tshais: feem ntau fortified nrog phosphatates.
- Cov Khoom Muag Ci: Raws li cov tshuaj uas muaj poov xab cov neeg sawv cev.
- Jams, Jellies, thiab khaws cia: rau kev tswj hwm thiab pH.
- Kho cov nqaij: rau cov dej noo kev tuav, tsw, thiab khaws cia.
- Flavored dej thiab dej haus muaj kev lom zem: rau tartness thiab raws li cov khoom noj muaj txiaj ntsig.
- Hmoov rau cov dej haus: rau cov tsw thiab acidity.
Kev Nyab Xeeb Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv: Cov kev cai muaj kev muaj tiag
Khoom noj khoom haus qib phosphoric acid siv nyob rau hauv cov kev txwv tsis pub nyob rau hauv cov kev txwv feem ntau pom tau tias muaj kev nyab xeeb (gras) los ntawm FDA thiab pom zoo siv hauv EU. Cov kab lus tseem ceeb yog "Cov Khoom Noj Qib" thiab "nyob rau hauv kev txwv."
Txawm li cas los xij, nws siv thoob plaws, tshwj xeeb hauv cov khoom qab zib, tau ua rau kev sib tham txog kev noj qab haus huv:
- Pob txha kev noj qab haus huv & osteoporosis: kev tshawb fawb txog kev pom zoo, feem ntau muaj phosphoric acid) kom muaj peev xwm txo cov pob zeb hauv av, tshwj xeeb hauv cov poj niam laus. Txawm li cas los xij, cov pov thawj tsis tau xaus. Cov neeg thuam tawm tsam cov nyhuv yuav cuam tshuam ntau dua los hloov cov calcium {2} Tsis muaj cov tshuaj phosphoric acid nws tus kheej ncaj qha calaching calcium los ntawm cov pob txha. Lub teb chaws qhov chaw noj qab haus huv (NIH) hais tias nyob rau hauv kev noj zaub mov zoo, phosphorus los ntawm cov kev pheej hmoo mus rau kev pheej hmoo rau cov neeg noj qab haus huv.
